Solved Custom inventory on HashMap problem

Hi, I've got problem with custom inventory on HashMap. I know how HashMaps works and yes I searched google so many times and I can't find solution to my problem yet. So my main problem is that when player joins server it put's him in HashMap<UUID, Inventory>. In player interact event when player right or left click emerald it gets this specific inventory and put inside pre maid ItemStack with player statistics in lore (yes statistics are also in HashMaps). I will explain my problem on two players Bob and Tom So if Bob open menu ItemStack shows Bob's statistics if he close and opens menu again everything works fine, but when Tom joins server and open menu it show Tom's stats (and at this point magic starts). So now when Bob open's menu it will show somehow Tom's statistics and I have no idea why this is not working properly when both players have different inventories?
This is part of code form PlayerJoinEvent:

Code:

HashMaps.pinv.put(p.getUniqueId(), Bukkit.createInventory(null, 9, "Main Menu"));

this is part of code from PlayerInteractEvent:

Code:

HashMaps.pinv.get(p.getUniqueId()).setItem(2, MainMenuPage.getInstance().playerStats);
p.openInventory(HashMaps.pinv.get(p.getUniqueId()));

Probably it's something totaly stupid but i can't find the problem :O
Sorry for my english

 

Show more code. You are not showing how you are building the inventories which is almost certainly where your problem is.

My guess is you are not creating unique ItemStacks for each player inside each inventory but rather references to previously created ItemStacks.

"put inside pre maid ItemStack with player statistics in lore" - this is your issue. Update the lore when a Player opens an inventory with their stats. Make sure when you add ItemStacks to the inventories when you create them that you are creating NEW ItemStacks for EACH item you place inside.

Otherwise you are just passing references to an ItemStack and it will change for all inventories if you do this.

 

@nj2miami Ok, thanks I'll check that but it means i will need to change a lot with ItemStacks I think i will never serch for problems in itemstacks

@nj2miami Thanks a lot it works now
